Amit, you have shown us the code that seems to work, but in general you

Good advice from Steve. Storable bas the benefit of being fast, but the
downside of not being human readable, if that is a requirement. Other
modules, such as Data::Dumper, Data::Dump or even XML::Simple would be
more human readable if not as fast. There are not doubt other modules
that can be used to good effect. It looks like your problem has been
solved a number of times, and in different ways. You could be spoiled
for choice.
